This invention relates to a cured in place liner system and methods for internally lining an existing pipe with a cured in place liner system. A variety of circumstances exist in which it is desirable to line a pipeline. For instance, in the municipal area, it may be necessary to line a water distribution pipes to form a rehabilitated flow path. A similar need exists in other industries, such as in the chemical pipeline industries. Conventional pipe lining operations require use of components of the existing pipe system to form the rehabilitated flow path. For example, the liner may depend on a seal with the existing pipe to form a rehabilitated fluid-tight flow path. It is desirable to provide improved systems and methods to rehabilitate a pipeline.
